Help - Get the product of the numbers between 1 and n?

How can I change this code to get the product of the numbers between 1 and a variable n. Here's the code, and I can just get the n's square.

    Function product(ByVal n As Double, ByRef i As Double)

        Dim a As Double

        For i = 1 To n

            a = n * i

        Next

        Return a

    End Function

Thanks.

well, right now you are reseting the varible "a" to a new number everytime your loop runs.

you need to add the value to a, here's how i would do it.

Function product(ByVal n As Double, ByRef i As Double)

       Dim a As Double

       a = 0

       for i = 1 To n

              a = a + (i*n)

       Next

       Return a

End Function

not sure if that's what you are looking for. Also, this looks like homework....please don't let it be homework, mainly because posting homework questions is against the forum rules.

Thanks, no, it's for myself. I'm trying to learn vb from an old book, but I didn't know what to do.
